The more I tried to stop myself from coming, the bigger it got. In the end, I orgasmed. Then she moved away from me.

A moment later I heard a gasp from Katie, and I knew what was happening even though I could not see it. I held a mental picture of the Nun's finger in Katie's pussy and then I heard her voice say, "Another non-virgin." Then I could hear the finger making wet noises in Katie's pussy, until Katie gasped from her own orgasm.

Sister Mary Katherine walked around licking her fingers, saying "We have two sluts here in our sacred school. So Sister, how should we punish these sluts for their immoral behavior?"
